The plug is forced inward until the upper.shoulder comes in con- Y tact with the uppei` portion ofthe packing-ring and forces the same against `tl1efea't. thereby further compressing' the elastic packii1g-ling and producing an air-tightjoint or seal at the l By this construction a positive airtight connection and a perfect seal is provided irrespective of the imperfections and inaccuracies present in such Jars. K

The plug is provided at its upper end with c a .head or enlargement l), and the distance bc- Q tween the upper shoulder and the lower face i ot' thdhead or enlargement is greater than the depth of the annular recess 3 to space the head or enlargement from the neck of the jar when the latter is scaled; as shownin Figs. 2 and A knife-blade or similar tool ma)- be readilgv inserted-in the interveningt space 11 between the lower face of the enlargement 10 and the 'upper edge of the jar. The plui,r is readily removed by lifting one side and thereby permitting air to enter the vacuum within the jar. rlhe jars are sealed while their contents are Aheated and while the'space between the contents and the plug is tilled with steam or vapor, and assoon as thc jar cools the vapors condense, thereby forming a vacuum and drawing,r the plu g more tightiy against the seat of the jar. i

When the plut,r is forced inward into the neck of the jar, the lower or inner portion of the'elastic packing-ring is frietionally engaged and compressed by the plug as soon as the lower shoulder passes the seat. This operation causes the plug to slip through the packing-ring, 'which con forms to the configuration of the neck of the jar, and when the upper shoulder engages the packing-ring the latter is spread over the seat,and the jar is effectively sealedfu 'l`hc sealing action of the device may be increased h v providing an upwardly-projecting beveled rib 12, as illustrated in Fig-3. The oppositebv beveled or tapered rib l2 is adapted to be partialhv embedded in the lower face of the upper or outer portion of the elastic packing-ring, and the latter is tightly compressed against the jar and the beveled face of the upper .shoulder and a positive seal is provided. This construction is especially adapted for receptacles havincr more or lr-ss irregularities in the engaging faces of the neck and the plug. .p

ln Fig. 6 of the drawings is illustrated another modification of the invention, in which-` is curved at 14, as shown in Fig. T ofthe draw- `1ngs. The Jar 15 is constructed suhstantiallY Atem-ling outward. over the seat ofthe tar an adapted to compress the upper or outer portion of the elastic pacI-:ing-ring against the same. '.l'he lower portion of the plug` is con,- structed similar to that before described, and j the packing-ring is` placed on t e saine end introduccdintotliejar,asbefore xplained. The upper or outer portion of the packing-ring is adapted to lie Hat against tho shoulder orseat ot' the jar, and the upper horizontal shoulderof the pluirispreferabl) provided with adepending rib 1H, which is embedded in the upper face of the elastic packing-ring, as illustrated in 'especially designed for jars having more oxJ less nicks, notches, or similar imperfections at the shoulder 0r scat produced hile the jars are heini,r manufactured.
